DUST DFLECTOR AND CATCHER FOR RADIATORS.

Specification of Letters Patent.

Patented April 17, 1906.-

Application filed February '7. 1905. Serial No. 244,610.

To all whom it mag/concern:

Be it known that I, ROLLYN HAWKINs, a citizen of the United States,residing at Indianapolis, in the county of Marion and State of Indiana,have invented certain new and useful Improvements in Dust Deflectors andCatchers for Radiators, oi' which the following is a specification.

This invention relates to improvements in d ust-catchers for radiators.

The dust and disease germs which are carried on peoples shoes from ourstreets and are left on the carpets and oors in all residences andpublic buildings are kept in circulation in the air currents that passup through radiators in buildings heated by steam or hot water. Allradiators when heated draw the dust -laden air from the floors upbetween the sections, thence to the top of the radiator, from whence itis diffused against the wall directly above the back oi the radiator andupward to the ceilinor and outward into the room. The ilth ilack dust isthereby deposited on the wa ls, oeilings, draperies, furniture- --infact, on all objects in the room, and even upon the food when that isleft uncovered. This dust is not only very injurious to thewall-decorations and draperies, but is often heavily laden with germsthat spread disease. It is generally found necessary to annuallyredecorate the walls and ceilings in steam and hot-water heatedresidences, flats, and other buildings. Numerous radiator' shields anddeilectors have been invente and tried and have uniforml failed for thereason that dust when thus shielded or deflected into the room is simplykept in circulation and will eventually settle on the draperies anddecorations.

The ob'ect of this invention is to separate the dust iirom the air andretain it in a suitable holder, from which it can be easily removed witha damp cloth without the inconvenience of removing the dust-catcher fromthe radiator.

The object also is to provide a means whereby the dust-catcher can bereadily removed from the radiator by simply lifting it therefrom when itis desired to do so for any purpose.

The object also is to'provide means whereby the dust-catcher canbe ttedto all sizes and styles of radiators. y

A further object of the invention is to provide an adjustable apron atthe rear of the `dust-catcher which can be set with its lower edgeagainst the wall, where the radiators are set farther than six inchesaway from the wall, it not being necessary to adjust the apron when thelower edge of the latter is under six inches from the wall.

The object of the invention also is to rovVide a wa l-protector to beplaced back o the radiator where the walls are uneven by reason ofpanels, casings, and the like, which keep the lower edge of the apronfrom fitting close thereto.

I accomplish the objects of the invention by the mechanism illustratedin the accompanying drawings, in which- Figure 1 is a detail inperspective ofthe upper end of the radiator, showing my dustcatcherattached in o erative position. Fig. 2 is a vertical section o same.Fig. 3 is a detail in side elevation of that part of the removable,fastening device which is iixed to the apron.

Fig. 4 is a detail in front view of the entire mechanism used forremovably securing the dust-catcher to the radiator, the view showingsaid parts detached from the dust-catcher and from the radiator and alsoshowing thel same without the front clamp and connectingrod. Fig. 5 is aview in vertical section of a radiator equip ed with my dust -catchenapron, and wal -protector. Fig. 6 is a detail in horizontal section onthe lines 6 6 of Fig. 5. Fig. 7 is a detail in side view ofthe lower endof one of the end plates of the dustcatcher; and Fig. 8 is a detail' invertical section of the wall-protector, showing the means by which itsupper end is secured.

Like characters of reference indicate like parts throughout the severalviews of the drawings.

9 represents the coils of a radiator for steam or hot water, of usualconstruction', and 10 is a holding -plate, preferably half-round incross-section, to fit between adjacent pairs of radiator-coils andcontact with the adjacent members of the pair, between which it isplaced. 11 is a bolt which is passed horizontally between said pair ofcoils, first three h a clamping-plate 12, placed ,at the front of theradiator between said same pair of coils, and

then through the plate 10 in the manner shown in Fig. 2, and then saidbolt is held by screwing the nut 13 upon its threaded end. Theholding-plate 1() will preferably have a vertical ,series of bolt-holesin order that the bolt 11 may be placed higher or lower in the radiatorto avoid the connecting members of the radi- IOC IIC

ator lpairs or other obstructions that are common y found and which varyin positions with the different styles of radiators in common use. Theholding-platel will preferably be concave to let the nut in past itsedges; The plate 10 will have a top extension, which is bent at rightangles to form Kthe horizontal member 14, that will occupy a positionupon formed therein.. The grooves are in pairs located opposite eachother on the front and back sides, respectively, as shown at 16 in thedrawings. l

17 is the hood: of my dust-catcher, which may be made out of sheetsteel, copper, brass, or other suitable material, plain or crimped, thecrim ed material being preferable for the reason t at it will hold itsshape better, and any buckling of the metal will not be as noticeable aswith plain sheet metal.

1'8 represents the hood ends, which are made out of cast metal and arestiff and rigid in construction to ive shape and rigidity to the hoodwhich is astened to these ends.

19 is a slotted holder which is fastened, preferably by rivets, to theunder side of hood 17.

'This holder has a downwardly-projected member'provided with the underend slot 20. The slot 20 will preferably have inwardlyslopingsides andwill be wide enough to receive said flange, and in operative positionthe inner end of the slot w1ll bear upon the to of the flange, therebyforming the principa sup ortfor' the hood 17 Arocking movement o thehood is prevented by the widening of the edges of the slot into flan es,as shown in Figs. 3 and 4, which give a su cient bearing a ainst thegrooves 16 to hold the hoodri id yinposition. Lon itudinalmovement o thehoo'd isv revente by the formation of lugs 21, whicli are extendedinwardly from the sides ofthe slot 20. These lugs entcr the grooves 16in the flange of the head 15. The length of the flange is such as toreceive a plurality of grooves in order that the holder may be made tofit at any part of the length of the flange without any specialadjustment of the distances apart of the heads 15 at each end of theradiator. This is important 'because the thickness of the coils may varyconsiderably in different makes ofl radiators, which would make itextremely difficult to place the heads e .ually distant from each otherin all cases. AJugs 21 are preferable to flanges for the reason that thelugs will adjust themselves without binding in the grooves underconditions that would cause a flange to bind. While I have shown twolugs justable extending in from each side ofthe slot, I'have found thatonly one is necessary, and in practice only use a single lug.

The front of the hood 17 is bent downwardly into the half-cylindricalroll 22. lt is then bent upwardly adjacent to the edge to form themember 23, and the edge of that member is bent toward the front to formthe horizontal ortion 24. This forms a ocket, as clearly siiown in Fig.2,- into whichl t e dust and dirt are guided by the under side of thehood, and theescape'ofthe collected matter is prevented by the saidhorizontal member 24. Thisconstruction ff rms a very important featureof my inverion. The back edge of the hood is bent d: Iw .i to form theapproximately vertical member 26, and the edge of that member is bent tothe rear to form the member 27 to make a close fit against the wall whenthe radiator lstands uite close thereto; but when the radiator is ocatedre' mote from the wall, as shown in Fig. 2,. an apron 29, which isadjustablein its position, as shown in dotted lines inFig. 2, isrequired to direct the current ofair rising between the radiator andwall into the dust-catcher. This `apron is formed out of sheet metal,with a top roll or bead toreceive lugs 30 from the plates 18 of thehood, thereby forming a inge connection which makes the apron `ad-Thevplates 18 are provided with openings to receive the'bolts 31, bywhich plates 34 at the ends of the apron are pivotally connected, andthe plates 18 have the slots 32 concentric with the holes for the bolts31.

the plates 34 have overlapping extensions 35, through which the bolts 31are passed. The extension 35 has the bolt 38, which passes through theslot 32 in the plate 18. and by means of a nut on the threaded end ofsaid bolt the plate may be tightened so as to lock plates 34 in any'adjustment that may be given. These'plates have pairs ofinwardlyprojected lugs 33 to receive the ends of the The ends of theplates 34 are made con- -cave to fit the rounded ends of plates 18, and

apron and raise and lower the apron by the raising and lowering of theplates. Thus when the radiator is awayfrom the wall so far that thedust-hood does not prevent airn currents from rising .between theradiator and wall the apron 29 b the means above described can be set toc ose the distance in the `manner as shown in Fig. 2.. The apron 1shinged as close to the hood as possible, so as to make the joint tightbetween them and is thereforeeccentric of the pivotal attachment of' theplates 34. The apron is loosely held between the lugs, so as toslidefreely between them in adjusting the apron.

In Fig. 5, 40 represents a molding which extends out from thel wall, soas to interfere wl'th the proper adjustment of the apron. Wmdow-casings,pipes, and other obstructions frequently occur which makes it nerr-ssaryin order to adapt my device to all localities to provide a false wallbetween the real wall and the radiator, which will be connected up withmy dust-catcher, so as to direct the heated currents in front of it intothe dust-catcher and prevent the heating of the air between the falsewall and wall proper. This false wall, as shown lin Figs. 5 and 6,comprises a vertical sheet-metal plate 41, thev lower end of which restsupon the floor and the upper end of which extends up into the range ofadjustment of the apron 29. It also comprises a sheet of corrugatedmetal 43, which is laced between the late 40 and radiator an isseparated there om by the horizontal metal bars 44, the bars 44 and thetwo metal plates being riveted together, as shown in Fig. 6.- Thecorrugated metal^43 terminates at a suitable distance above the floor,as shown in Fig. 5, to allow the free entrance of air-currents into theopen ends of the ilues formed by the corrugations, and the circulationor flow of air from the rear to the front of plate 41 is permitted by aformation of holes 46 through plate 41 adjacent to the lower end of thecorrugated metal sheet43.

The upper end of the above-described false wall is held in positionagainst the radiator bymeans lof the metal straps 48, which are fastenedby means of the bolt 11 to the radiator and which extend from thence tothe top of the false wall and are bent across and down at the back ofthe wall in the manner as cleaily shown in Fig. 8.
